The Y-Knot® utilizes an ~3mm-wide, flat-braided Hi-Fi® suture construct as an anchor body with one or two #2 Hi-Fi® Sutures interthreaded. The anchor
is inserted into a 1.3mm (for single-loaded) or 1.8mm (for double-loaded) pilot hole. The #2 Hi-Fi suture limbs are then pulled back to set the anchor: it compresses vertically and expands
laterally, and becomes seated in the bone. The Y-Knot® fixates circumferentially within the pilot hole for a more secure repair.

Put Simply: We put more material in a smaller hole for a more secure repair achieved by 360° FormFit™ Fixation.

Despite being the smallest of these commonly used labral repair anchors, the Y-Knot Flex 1.3mm anchor outperforms the others with 250N of pull-out strength. In-house testing of the
1.8mm showed even higher pull-out strength at 380N.*

The Y-Knot™ outperforms competing all-suture anchors with less than 1mm displacement under cyclic loading.*

Displacement (aka “creep”) is what surgeons are frequently concerned with when they question the strength of an all-suture anchor repair. E.g. “It feels strong when I insert the anchor, but
how do I know it won’t migrate over time?” The Y-Knot anchor outperforms the Juggerknot when it comes to this critical factor.

Instrumentation

Like other labral repair anchor systems, the instrumentation for the Y-Knot Flex system is comprised of a drill bit to produce a pilot hole, drill guides to aid in drilling and anchor insertion,
and obturators and trocars to facilitate introduction of the drill guides into the joint. The flexibility of the system provides unprecedented surgical delivery options beyond the basics,
including curved and percutaneous approaches to the repair site.

Drill BitsEach drill bits is flexible, made of Nitinol, and has a plastic disc at the proximal end to ensure proper drilling depth (21mm). The disc is color-coded to the corresponding anchor.

Standard InstrumentationReusable fishmouth and crown-tipped drill guides are available for the Y-Knot Flex. These have robust shafts, but are slimmed down at the tip to enable precise positioning of the drill
bit and anchor.

Curved Delivery InstrumentsA reusable guide with a distal curve may provide your surgeon improved access to the repair site, especially for posterior SLAP and inferior Bankart repairs. It may also provide for more
perpendicular approaches to the glenoid. The guide has windows optimally placed on the guide.

Percutaneous Delivery PacksA series of options are available to introduce drill guides percutaneously (directly through the skin without use of a separate cannula). The Y-PERC consists of a spinal needle, guide
wire, and a switching stick over which the reusable Y-Knot Flex Guides can be placed.

In addition to the spinal needle, guide wire, and switching stick, Y-PERC13 and Y-PERC18 each contain a separate disposable percutaneous drill guide with a T-handle that is sized specifically
to the 1.3mm or 1.8mm anchor, respectively. These T-guides can be used with the provided trocar stylet to insert the drill guide directly into the joint in a single step. They can also
be used with the provided cannulated stylet to be inserted directly over the guide wire.

Features & Benefits

Feature

Benefit

Clinical Relevance

Small sizes
- 1.3mm single-loaded
- 1.8mm double-loaded

Requires less bone removal when drilling pilot hole*
Enables more points of fixation where they are needed most

• Maintains structural integrity of glenoid/acetabular rim
• Preserves natural anatomy
• Affords better revision options (can use a smaller bail-out anchor)
Enables surgeon to place anchors where he/she would like them for a more optimal repair7

Anchor is comprised entirely of Hi-Fi® Suture

No hard-loose bodies in the joint if anchor is pulled out
Stronger than polyester*

Less risk for articular damage in the joint after surgery if anchor dislodges
More strength and resistance to breakage in the repair

Enables surgeon to place anchors where he/she would like them, especially for inferior Bankart and posterior SLAP anchors.

Percutaneous Delivery

Enables creation of additional entry points and angles without a full-sized portal

Provides surgeon additional minimally invasive approach options.

Hi-Fi® suture

Single or double-loaded options
Does not have a solid core (unlike Fiberwire)Completely non-absorbable (unlike Orthocord)

• Supports surgical techniques requiring one or two stitches from a single anchoring point
• Results in lower knot stacks, which may reduce risk of humeral head abrasion and intra-articular irritation
• Less abrasive on surgeon hands and soft tissue8Repair construct will not loosen after partial absorption of suture

Specifications

Each Y-Knot® Flex anchor is loaded between the tines of an inserter at the time of manufacturing. This is a precision process; the anchor should not be reloaded if it becomes dislodged from the device.
